Attack details

Blind SqlInjection

SQL injection is a vulnerability that allows an attacker to alter backend SQL statements by manipulating the user input.

An SQL injection occurs when web applications accept user input that is directly placed into a SQL statement and doesn't
properly filter out dangerous characters. 

An attacker may execute arbitrary SQL statements on the vulnerable system. This may compromise the integrity of your database and/or expose sensitive information. 

Depending on the back-end database in use, SQL injection vulnerabilities lead to varying levels of data/system access for the attacker.

It may be possible to not only manipulate existing queries, but to UNION in arbitrary data, use subselects, or append additional queries. In some cases,
it may be possible to read in or write out to files, or to execute shell commands on the underlying operating system.

Certain SQL Servers such as Microsoft SQL Server contain stored and extended procedures (database server functions). 

If an attacker can obtain access to these procedures it may be possible to compromise the entire machine.
